Photoelectric sensor lot Infrared IR correlation count sensor module
RM10.00
Correlation photoelectric Infrared count sensor module is a high-quality infrared Counter module at a very cheap price which comes with tiny size and integrated LM 393 chip.
Description
It works as,
1. The OUT pin is a low level when there is no object between the photoelectric sensor, and the red LED is lit.
2. The OUT pin is a high level when there is an object between the photoelectric sensor, and the green LED is not bright.
3. The OUT port can be connected to MCU directly, Than MCU can calculate how many circles the smaller car has run per unit
Note: The sensitivity is not adjustable.
